I don't know, I haven't found the spell yet or the trainer for it. But I'm assuming no, because I have a Intelligence of 42 and Soul Spear required 36 already. Since you can already equip a strong sword (I made the mistake of adding lots of points to Strength and Agility to use the Black Knight Sword) that already scales with Intelligence, I'd recommend focusing on Intelligence and Endurance. My point distibution is something like +2 Endurance, +6 Intelligence, +1 Vitality, +1 to another stat for every 10 points.
You're going to have a pretty hard time anyways at the start though, due to the combination of low Vitality, Endurance, and the fact that you have to keep a distance from your enemies. Have fun!
